SPRING ASSEMBLY Filed July 7, 1955 INVENTOR. 4 Z/J/YQ/ Q Ka/A/PJ 7- wmaw United States SPRING ASSEMBLY Leland 0. Collins, Detroit, Micln, assignor to L. A. Young Spring & Wire Corporation, Detroit, Micln, a corporation of Michigan Application July 7, 1953, Serial No. 366,431 9 Claims. (Cl. -266) This invention relates to improvements in spring assembly. The invention is well adapted for use in spring seat cushions, backs and the like for motor vehicles, furniture and the like.

' The main objects of this invention are:

First, to provide a spring assembly in which the helically coiled springs are efiectively supported in an upright position on base wires or rods, providing connections which are substantially noiseless.

Second, to provide a spring assembly having these advantages which is economical in its parts and in the assembly thereof.

Objects relating to details and economies of the invention will appear from the description to follow. The invention is defined in the claims.

A structure which embodies the features of the invention is clearly illustrated in the accompanying drawing, in which:

Fig. 1 is an inverted fragmentary plan view of a spring assembly embodying the invention with certain portions thereof in completely assembled relation and other portions illustrating stages in assembly.

Fig. 2 is a fragmentary perspective view.

Fig. 3 is a top fragmentary view illustrating steps in assembly of the parts.

The embodiment of the invention illustrated comprises a border frame designated generally by the numeral 1 and desirably formed of wire or light rod including side members 2, 2 and end members 3, 3. The longitudinal base bars 4 are secured at their ends to the end members of the border frame and are arranged in transversely spaced parallel relation. These base bars have upwardly projecting offsets or loops 5 spaced longitudinally thereof, the loops being desirably transversely aligned as illustrated. The transverse base bars 6 are connected at their ends to the side members of the border frame and are connected at their crossing points as indicated at 7 to the longitudinal base bars. It will be understood that the terms longitudinal and transverse" are used for convenience in description and that the assembly may be of any desired proportions. A small structure only is illustrated; that is, there are usually more than three springs in transverse alignment.

The helically coiled conical springs 8 terminate in bottom coils 9 which are disposed upon the base bars 4 in embracing relation to the loops 5 therein. The loops or offsets 5 are preferably formed to provide abrupt shoulders 10 which the coils engage, thereby preventing any longitudinal shifting of the coils on the base bars. The coils terminate in arms 11 of a length exceeding the spacing of the base bars 4. These arms 11 terminate in upturned angularly disposed portions 12, the bends or angles 13 of which are engaged with the bight portions of the loops 5 when the parts are fully assembled as shown in the drawing. This upturned end facilitates assembling with the arms over the bottom coils and under the loops.

The arms 14 of one row of border springs terminate 2,735,114 Patented Feb. 21, 1956 in ofisets 15 connected to the adjacent border frame by means of clips 16. The other row of border springs are secured to the base member adjacent the other side member 2 by means of the locking members 17 which have extremities of the same shape as the arms 11 integral with the springs and are inserted through the loops and over the bottom coils of the body springs.

In Fig. 3 I illustrate the steps in assembly. The arms 14 of the border springs adjacent one frame side member are secured thereto as has been described. The springs 8 of the adjacent row are then mounted on the adjacent base bar, the arms 11 of the springs being engaged with the previously mounted springs. This may be readily effected by inserting the ends of the arms through the loops and over the bottom coil with the springs in a tilted position as illustrated in Fig. 3. With the arms engaged with the bottom coils and with the loop, the spring is swung to an upright position over the loop of the supporting base bar. This manipulation is continued for each spring. The last row of border springs to be assembled is secured by means of the locking members or fastening means 17.

In assembly the spring which is to be locked down or secured is held down upon the base bar upon which it is mounted with one hand while the locking and succeeding spring of the assembly is manipulated to bring its arm 11 into locking position. The clips 16 are desirably formed of sheet metal and are applied by a plierlike tool commonly used in applying clips in spring assemblies. The springs are securely retained against movement in any direction on their supports and, as stated, the accompanying drawing is for illustrative purposes.

The invention is desirable for use in a Wide range of commercial structures which I have not attempted to illustrate as it is believed this disclosure will enable those skilled in the art to embody or adapt the same as may be desired.
